You want to eat a lot of protein. Things like peanut butter. Protein will definitely make you gain muscle if you exercise along with eating it.

Really you have taken a very right decision in right time. To keep body healthy and muscle growth you have to be serious about following things:
1- Stay on proper diet.
2- Take food more times in a day but must eat low carbohydrate, Low-calorie food. Avoid foods containing saturated fat, added salt, added sugars and alcohol.
3- Drink lot of water
4- Physical exercise which is mostly needed for you. Lifting weights, Running, walking briskly, biking at a casual pace etc are mostly needed.
Also supplements are very important components for human body to reach all needs for body and gives a healthy living also helps for muscle growth. From one of my friends I came to know about egg white and after use I got very good and effective results. For any details you may visit “eggwhites247.com”. Thank you.
